REZIME
Kriptologija je pronašla svoje mesto u primeni kod mnogih nauka i institucija.Svakoj
instituciji je potrebna privatnost.Pogotovo onim institucijama koje su od velikog znaĉaja
za ljude i drţavu.Mene je najviše zainteresovala kriptološka primena u vojne
svrhe.Vojska,kao oliĉenje drţave i njenog uticaja u društvu,oduvek je morala da odrţava
privatnost.Tome svedoĉe brojne vojne tajne ĉija je sadrţina varirala od jednostavnog
vojnog poloţaja do poverljivih vojnih istraţivanja.
Cilj te tajnosti je bio strah da će druge vojne sile iskoristiti njene prednosti,a to znaĉi da
ta vojska neće biti dominantna na bilo koji naĉin što je upravo i cilj vojnih sukoba.Vojni
šifratski sistemi su se morali razlikovati od javnih zbog toga što je vojska imala mnogo
veću intimnost.Oni su se meĊusobno razlikovali,od prikazivanja slova taĉkama,do
korišćenja drugog,nepoznatog jezika(na primer,ameriĉki vojnici koristili su indijance kao
kurire,jer je njihov jezik bio neshvatljiv drugim vojskama).
Naravno,vojna kriptologija ne moţe da proĊe bez Enigme,mašine koju su Nemci koristili
tokom 2. svetskog rata.Vojska je nailazila na mnogobrojne prepreke u kojima je dobra
organizovanost imala kljuĉnu ulogu.Kriptografski i kriptoanalitiĉki algoritmi su imali sve
veću upotrebu u ove svrhe.Vojna kriptologija za mene predstavlja najbolju primenu
kriptologije,i baš po tome trebalo bi da joj se da najviše unapreĊivanja.

SUMMARY
Cryptology has found its place in the pratical application in other disciplines and
institutions. Every institution needs privacy.Especially those institutions which are of the
great importance for the people and the state.Of the biggest interest to me was the
application of cryptology for the military purproces.The army,as a miror of the strength
of a state and its influence on the society, has always needed to preserve its privacy.This
can be seen in numerous military secrets which included various things,from the military
position to the military experiments.
The aim of this secrecy was the fear that other military forces would tawe the advantages
of any way,and this is actualy the purpose of armed conflicts.The methods of codifying in
the these other methods were available to the public and likewise,to the opponents.The
methods themselves differed a lot,from presenting the letters with the dots,to using some
other,unknown language (American soliders,for example,used Indians as
couriers,because their language was incomprehensible to other armies).
Of course,when talking about military cryptology,Enigma,the machine used by Germans
in World War 2,has to be mentioned.The army experienced numerous difficulties,and a
good organization had the key role then.Cryptographic and cryptoanalytical algoritms
were more and more used for these purposes.Military cryptology represents the best

practical application of cryptology,in my opinion,and this is the reason why it should be
constantly advanced.
